Featured are a device (20) and method for the detection of counterfeit pharmaceuticals and/or packaging therefore. Counterfeit pharmaceuticals are detected by visual inspection upon exposing a suspected counterfeit pharmaceutical to one or more light sources having different wavelengths, and observing the differences in color and/or brightness between the suspected counterfeit and a genuine pharmaceutical/packaging. In further embodiments, a image acquisition device acquires an image showing color and/or other visual effect(s) brightness of the suspect counterfeit and this image is compared to an image of a authentic pharmaceutical/packaging.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A device for detecting a counterfeit pharmaceutical product, comprising: a plurality of light sources configured to emit light at a plurality of different wavelengths onto an object potentially including a suspect product, at least one of the plurality of different wavelengths not being matched to an excitation frequency of a light-sensitive compound; at least one image acquisition device; and at least one display for observing a color comparison of an image of the object illuminated by the plurality of different wavelengths and an image of a known product under illumination of the same wavelengths.
2. The device of claim 1 further comprising a housing and wherein the plurality of light sources and the at least one image acquisition device are coupled to the housing so that the plurality of light sources and the at least one image acquisition device are maintained in fixed relation to each other while the object is being illuminated.
3. The device of claim 1 , further comprising a light source control device for controlling respective ones of the light sources.
4. The device of claim 1 , further comprising a communication device configured so as to allow communications between the detection device and a device that is external to the detection device.
5. The device of claim 1 , wherein the device further comprises two image acquisition devices.
6. The device of claim 1 , wherein said image acquisition device includes a filter.
7. The device of claim 1 , wherein said image acquisition device is a CCD array.
8. The device of claim 1 , wherein at least one of the plurality of light sources is configured so as to emit light having an infrared wavelength.
9. The device of claim 1 , wherein at least one of the plurality of light sources is configured so as to emit light having a visible wavelength.
10. The device of claim 1 , wherein at least one of the plurality of light sources is configured so as to emit light having an ultraviolet wavelength.
11. The device of claim 1 , wherein said light sources are LED light sources.
12. A device for detecting a counterfeit pharmaceutical product, comprising: a housing; a plurality of light sources coupled to said housing configured to emit light at a plurality of different wavelengths, wherein said light sources includes at least one infrared wavelength, at least one visible wavelength and at least one ultraviolet wavelength, at least one of the plurality of different wavelengths not being matched to an excitation frequency of a light-sensitive compound; at least one image acquisition device; at least one display for observing a color comparison of the image of the object illuminated by the plurality of different wavelengths and an image of a known product under illumination of the same wavelengths; and a plurality of buttons controlling respective ones of said light sources.
13. A method for detecting a counterfeit pharmaceutical product, comprising the steps of: selecting a wavelength or wavelength range of light; exposing a suspected counterfeit pharmaceutical product to light of said selected wavelength or wavelength range with a light source; viewing a color of said suspected counterfeit product upon exposure to said wavelength or wavelength range; and comparing the color of said suspected counterfeit product exposed to the wavelength or wavelength range to a color of a known pharmaceutical product exposed to light of the same wavelength or wavelength range; and determining a similarity of a composition between the suspected counterfeit product and the known pharmaceutical product without viewing a light sensitive marker.
14. The method of claim 13 , further comprising wearing colored goggles when viewing the pharmaceutical product.
15. The method of claim 13 , wherein said wavelength is within the visible, ultraviolet or infrared range.
16. The method of claim 13 , wherein the suspected counterfeit product and said known product are exposed to said light and viewed simultaneously.
17. The method of claim 13 , wherein the appearance of the suspected counterfeit product is compared to an image of the known product exposed to the same wavelength of light.
18. The method of claim 13 , wherein said pharmaceutical product is a tablet, capsule, vial and/or packaging components.
